|
|
* Test Name: quotactl03
|
|
*
|
|
* Description:
|
|
* quotactl(2) with XGETNEXTQUOTA looks for the next active quota for an user
|
|
* equal or higher to a given ID, in this test the ID is specified to a value
|
|
* close to UINT_MAX(max value of unsigned int). When reaching the upper limit
|
|
* and finding no active quota, it should return -1 and set errno to ENOENT.
|
|
* Actually, quotactl(2) overflows and and return 0 as the "next" active id.
|
|
*
|
|
* This kernel bug of xfs has been fixed in:
|
|
*
|
|
* commit 657bdfb7f5e68ca5e2ed009ab473c429b0d6af85
|
|
* Author: Eric Sandeen <sandeen@redhat.com>
|
|
* Date: Tue Jan 17 11:43:38 2017 -0800
|
|
*
|
|
* xfs: don't wrap ID in xfs_dq_get_next_id
